[19:26:06 CET] <durandal_1707> nobody can match with my skills!
[19:27:12 CET] <kierank> durandal_1707: why
[19:27:26 CET] <kierank> You are not cael
[19:27:27 CET] <kierank> Carl
[19:29:30 CET] <durandal_1707> None of my concern.
[19:31:36 CET] <j-b> Can you do the opposite?
[19:33:26 CET] <durandal_1707> what opposite?
[19:40:50 CET] <j-b> create atmos metadata :)
[19:41:23 CET] <j-b> also, do we render atmos correctly?
[19:41:54 CET] <JEEB> pretty sure there's N different types of audio under the moniker "dolby atmos"
[19:41:54 CET] <kierank> Yes, RE atmos
[19:42:07 CET] <JEEB> just like dolby vision is actually N different things as well
[19:42:08 CET] <JEEB> :D
[19:43:31 CET] <durandal_1707> i stil not found software that understand atmos
[19:45:25 CET] <durandal_1707> but iirc kostya said he looked at some binary...
[19:46:29 CET] <JEEB> Description: Media Foundation Dolby Digital Atmos Decoders.
[19:46:36 CET] <JEEB> DolbyDecMFT.dll
[19:46:39 CET] <JEEB> maybe?
[19:47:00 CET] <atomnuker> write a bsf to losslessly rotate jpeg images
[19:48:37 CET] <JEEB> durandal_1707: seems to come with good ol' windows now?
[19:48:48 CET] <JEEB> original file name: DolbyAtmosDecMFT.dll
[19:49:10 CET] <durandal_1707> windows 7?
[19:49:15 CET] <JEEB> 10 at least
[19:49:16 CET] <JEEB> 1809
[19:53:26 CET] <durandal_1707> i do not think it decodes to additional channel?
[19:53:35 CET] <JEEB> no idea what the flying fuck it does :D
[19:55:45 CET] <j-b> the one from Xbox1?
[19:57:45 CET] <durandal_1707> iirc there was some think like prohibiting atmos implementation to anything except allowed by dolby?
[19:58:18 CET] <durandal_1707> i do not want to be sued by those guys
[19:59:01 CET] <JEEB> they're not DTS
[19:59:09 CET] <JEEB> and as long as you're not legally bound by NDA
[19:59:20 CET] <JEEB> nobody gives a flying fsck
[19:59:37 CET] <JEEB> (As long as your implementation is kosher and doesn't copy dolby code)
[19:59:57 CET] <durandal_1707> it copies binary code
[20:00:26 CET] <durandal_1707> variables are a, b, c, d, ... x, w, y, z
[20:59:37 CET] <atomnuker> are the timestamps for the av1 chimera samples from netflix fucked?
[21:00:05 CET] <atomnuker> they seem to restart once every 2 or so seconds
[21:02:11 CET] <jamrial> atomnuker: yes, get the mp4 ones instead
[23:36:26 CET] <cone-577> ffmpeg 03Paul B Mahol 07master:57815cfad5c5: avfilter/vf_overlay: fix crash with negative y
